Re: Troubles with X1 Carbon 2018 (X1C6) TouchPad and TrackPoint under Linux

Then consider yourself lucky. I also updated the Kernel (4.20) and the BIOS (1.34) but my NFC touchpad realibly dies after resume from S3, which I enabled in the BIOS. I now switched to a MBP, which I still don't love because MacOS gives you a rather bad UX in my opinion, but at least the hardware works with the OS.

Now that I lost so much money and time on the X1C6, I would not risk to buy any other ThinkPad ever again. At least not until they'd sell one with Linux pre-installed or really make an effort to officially support it.

Re: Troubles with X1 Carbon 2018 (X1C6) TouchPad and TrackPoint under Linux

AaronMa from canonical is looking into the issue and has supplied a custom kernel for ubuntu which should fix the suspend/resume trackpoint/touchpad issues (at least it works for me).

 

The bugreport is here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791427

The specific comment with the download link is here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1791427/comments/94

 

He wants to upstream his patch if more could test/confirm that his changes resolve this issue.

Re: Troubles with X1 Carbon 2018 (X1C6) TouchPad and TrackPoint under Linux

Did anyone manage to enable pinch zoom on the X1 Carbon (2018) on Linux? What are the steps I should do to get a touchpad which is as much working as possible?

Re: Troubles with X1 Carbon 2018 (X1C6) TouchPad and TrackPoint under Linux

You could manually install Aarona Mas kernel deb files with "sudo dpkg -i ...". But the kernel is quite old (based on 4.20.rc3) and probably not suited  for everyday use. However, he just send his patches upstream: 

https://lkml.org/lkml/2019/2/20/700

 

So currently the best way would be to build a kernel yourself with the corresponding patch. Or wait until they are accepted and available in mainline. Then you could install a kernel from  https://kernel.ubuntu.com/~kernel-ppa/mainline

Does the v1.37 BIOS update help?

Today I just saw this update:

 

xhVF6WgLinux BIOS firmware update

Does anyone know what it does? I don't see any sort of changelong at https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-.... If it doesn't add support for WWAN, fingerprint reader, or the trackpoint, I'm not going to install it - who knows what it might break.

 

Also, how can Lenovo claim the ThinkPad is a Linux machine, when so many essential components are broken? No fingerprint reader. No TrackPoint. No WWAN.

Re: Troubles with X1 Carbon 2018 (X1C6) TouchPad and TrackPoint under Linux

After months without any troubles with sleep mode or touchpad on Ubuntu 18.10, the last updates ( I cant say if it was the firmware or another software update) it became unusable again. What helped me was this article:  https://github.com/BelBES/thinkpad_x1_carbon_6th_linux

 

I just had to do this:

 

  1. Edit the /etc/modprobe.d/blacklist.conf file and comment out following line:
# blacklist i2c_i801

 

Touchpad is working again!

Re: Troubles with X1 Carbon 2018 (X1C6) TouchPad and TrackPoint under Linux

@dandv: The changelog is online (look into the "ReadMe for BIOS Update Utility"). Both 1.36/1.37 only seem to address security issues:

<1.37>
 UEFI: 1.37
- [Important] Update includes a security fix.

<1.36>
 UEFI: 1.36
- [Important] Update includes a security fix.
- (New) Updated the Diagnostics module to version 04.05.000.

@kaeltab: What you experienced was first the removal of the blacklisting in order to support new hardware like our x1. However, due to regressions (which are now fix) it was readded again -> it stoped working for you/us without manually editing the blacklist (see https://bugs.launchpad.net/hwe-next/+bug/1786574 ). It should be removed again soon.

Back to the issue: the patches from aaronma are still not merged upstream and are waiting for review... However, I am using self-build kernels and both trackpoint/touchpad are working fine and survive every suspend/resume. (20KG model)
